A thermodynamically and variationally consistent class of damage-type cohesive models (2011, methodology): “The modeI ultimate strength of the material and the respective fract ure energy have been taken from [62]:T0,n = 5.”
The influence of adhesive constitutive parameters in cohesive zone finite element models of adhesively bonded joints (2009, methodology): “It has been shown that the shape of the traction law is not important in some cases (Valoroso and Champaney, 2006; Xie and Waas, 2006) and is important in others (Rots, 1986; Chandra et al.”
Strength prediction of single- and double-lap joints by standard and extended finite element modelling (2011, background): “It should be pointed out that the current implementation of the XFEM in ABAQUS is restricted to only one value of maximum strength or strain leading to the initiation of damage (by the maximum principal stress or strain criterion, respectively), which can be a severe limitation since the fracture pr”
